Very true. The most convenient and "gig-friendly" arranger I've ever had is the Korg PA4X.
However I do really enjoy playing the EA7, and a lot of it is the key touch--very light.
I used the EA7 last night and it was very well received.
Playing four hours a night in the same place week after week, sometimes a change is welcome, if only for variety and a slightly different sound and presentation.
I like that I can slip the EA7 in the bag and easily carry it.
